NCME folks, remember to stay for the Presidential Closing Reception on Saturday! Food and drinks, and you'll be able to see great work at the tail end of the program (and mine!). Maybe I'll see you on the redeye that night?😴

Excellent NCME webinar on testing policy, including "thinking big" about innovative assessment, the recent growth model RFI, and what we want to save (and improve) about NAEP. With Lily An, Allison Timberlake, Chris Domaleski, and Suzanne Lane via NCME's Committee on Informing Assessment Policy.

Congratulations to the next elected leaders of the National Council on Measurement in Education, @laurashamilton.bsky.social, Chris Rozunick, and (VP then President in 2027), Susan-Davis Becker! As I rotate off the board in April, I am proud to leave @ncme38.bsky.social in such good hands.

Teaching a new prep but it's an established class. The prior instructor assigned an annotated bib as the final. Given the agentic LLM chatbot of it all, I don't think I can do that. So now I gotta figure out how doc students can show me (and themselves) that they've learned some things.

At our NCME "Cafe AI" today, I heard how many colleagues are now 1) piloting oral exams, 2) requiring interviews for PhD finalists, and 3) using cold/warm-calling techniques in class. AI is inspiring new emphasis on communication skills. Thanks to NCME's "Educators of Measurement" SIG for hosting!

Your NCME vote (due 1/15) matters! Recent boards have: 1) invested in open access (e.g. EM5), 2) sued to protect US measurement data, 3) created new travel grants for students, 4) launched special conferences (AIME), and 5) created a 6-figure endowment. Vote to shape our future! @ncme38.bsky.social

This is a really lovely, even elegiac, reflection by Charlie on TACs as a form of oral tradition, "stories that must be told time and time again." More than stories, he also likens them to instruments in concert, benefitting from a conductor. I agree.
I hope NCME's list provokes further reflection.

Two recent posts by @andrewdeanho.bsky.social spurred my thinking about Technical Advisory Committees (TACs): TAC members are storytellers, passing on through oral tradition the key tenets of our field.

In my Week 1 assignment, I ask students to critique AI/GPT's answer to, "What is 'validity' in the context of educational measurement?"
Now that Harvard has updated its sandbox from GPT4.1 to GPT5.1, its answer is mostly right instead of mostly wrong.
Still, a good task! @ncme38.bsky.social
